For question 5 of the mentioned quiz, the answer provided indicates that the sum of elements in P U Q is 35 where P: set of all prime numbers less than or equal to 10 and Q: set of all positive even integers less than or equal to 10. I think the answer provided is incorrect because P = {2, 3, 5, 7} & Q = {2, 4, 6, 8, 10}. Their union would be the set {2, 3, 4, 5, 6, 7, 8, 10} which has 8 elements, making the sum of elements 45 and option A the answer. Can someone please explain this?
For question 13 of the same quiz, I think that either the options or the question needs to be modified because there seems to be a mismatch amongst the two. Can someone please clarify on this? Maybe Iām wrong in which case I would like to have a solution for this question.
